Title: Improvements in Electric Circuit Breaker With Current-Limiting Arc Extinguishing Means.
IPC: H01H9/30
Filed: 1967-11-04
Abstract: An electric circuit interrupter has a contact chamber 14A from which the arc is blown into an extinguishing chamber 14B through a constricted passageway which is stated to prevent cavitation and consequent retrogression of the arc. The constriction (Fig. 2) is afforded by shaped side plates 18, 20 of gas evolving material, which may be an acetal resin such as polyoxy. methylene. These plates 18, 20 together with arc runners 22, 24 carrying fixed contacts 25 are supported between moulded insulating walls 10A, 10B clamped together by bolts 63 the walls 10 may be of glass fibre reinforced alkyd resin or polymer. The tips of arc runners 22, 24, where the arc becomes stationary adjacent perforated insulating wall portions 46, 48, are provided with tungsten carbide inserts 30, 32. A silencer 12 is fitted over the outlets of the perforations 50. Conducting splitter plates are omitted from the chamber to reduce current chopping and a glass-melamine strip 58 is placed between the inserts 30, 32 to dissipate the recovery voltage peak when the arc is extinguished the strip 58 apparently becomes conducting in the presence of the arc. Connections 26, 28 are made to the contacts 25 in a manner such as to produce a strong magnetic blow-out field (Fig. 3, not shown). The bridging contact 36-38 is operated by overcentre mechanism through a releasable coupling as described in Specification 1,140,612, the coupling being released upon short circuit by an electromagnet acting directly on the contact rod 42 (Fig. 3A, not shown). The overcentre mechanism is releasable to open the contacts open lesser overloads by a bimetal 104 and electromagnetic trip 106.

Title: Method of making container closure construction
IPC: B21D43/00
Filed: 1971-10-23
Abstract: A tag ring element having a neck portion and a base portion and bordering the openings in container walls and methods and apparatus for at least partially forming the same during the application of the closure elements to the container walls, including means for automatically feeding and positioning blanks for such tag ring elements in position for securement during the securing of closure elements about said container wall openings. The tag ring elements may be preformed to varying degrees depending upon the means for holding them in the dies and may be of varying thicknesses, depending on whether they serve as the sole securing neck for securing closure flanges to container wall openings, whether they reinforce lightweight necks formed in the container wall, or whether they principally serve to provide eyelets for the attachment of various elements thereto. In a particular instance, the tag ring element flat blanks are fed into the dies which perforate container walls, draw necks up from the same form and secure the tag ring elements thereto, and secure closure flanges within such necks in one stroke of a press. Particular feeding and holding means for the tag ring elements for the automatic application of the same to container wall necks simultaneously with the application of the closure flange to the opening being formed, is provided in the instance of single stroke application of closures to the container walls.

Title: Electrical connector
IPC: H01K1/46
Filed: 1972-02-01
Abstract: An electric current carrying device such as an electric light bulb releasably receivable in a socket in which the device comprises a mounting base with an electrically conducting peripheral wall which may be of metal, an inner electrically conducting wall which may also be of metal in the socket for receiving the base in electrical contact, a helical screw thread on either the base or the socket wall and a plurality of circumferentially spaced spring tabs on the other wall. Each tab has a plurality of ridges spaced from each other in a direction parallel to the axis of the base or socket with each ridge lying along a section of a helix of substantially the same pitch and dimensions as those of the screw thread for engaging in the screw thread and retaining the base in the socket in its innermost position. The spring tabs are elongated and each has one edge that is parallel to the axis fixed to its wall as by being integral therewith and an opposite edge free in a cantilever construction and spaced from its wall with the result that when the base is inserted in the socket the tabs are compressed toward their wall to exert a holding spring action serving to retain the base in the socket and the helical section ridges on the tabs engage the screw thread at a plurality of circumferentially spaced areas not only to securely retain the base in the socket but also to provide good electrical contact between the walls and, as in the case of a light bulb, between the end contact members on the base and socket.

Filed: 1972-07-24
Abstract: In a hydrocyclone arrangement at least two hydrocyclones are spaced laterally apart with a filling chamber, an overflow chamber and an underflow chamber arranged centrically of the hydrocyclones. The filling chamber is aligned above the overflow chamber and the underflow chamber is aligned below the overflow chamber. The hydrocyclones are disposed obliquely of the vertical so that the underflow from each is directed into the underflow chamber. The filling chamber has a spherical configuration and a separate connection extends radially outwardly from the filling chamber to each of the hydrocyclones. A supply connection extends vertically upwardly into the filling chamber passing vertically through the overflow chamber and then extending horizontally outwardly or continuing to proceed vertically through the underflow chamber. Replaceable wear protection parts are positioned in the filling chamber and the filling chamber is constructed so that it can be opened for access to the wear protection parts. Further, the wear protection parts can be arranged to form enclosed wear indication spaces within the filling chamber connected through a tubular member with the outside atmosphere. Each of the filling chamber, overflow chamber and underflow chamber can be divided in two by vertical partitions for forming independent functional groups of the separate chambers each associated with a different hydrocyclone.
